16-48 ELECTRICAL SYSTEM
Electric Starter System
•
Tighten:
Torque - Starter Motor Through Bolts [A]: 5.0 N·m (0.51
kgf·m, 44 in·lb)
Brush Inspection
•
Measure the length of each brush [A].
If any is worn down to the service limit, replace the brush
assy.
Starter Motor Brush Length
Standard: 12 mm (0.47 in.)
Service Limit: 6 .5 mm (0.26 in.)
Commutator Cleaning and Inspection
•
Clean the m etallic debris off the between commutator
segments [ A].
NOTE
○
Do not use emery or sand paper on the commutator.
•
Check the commutator for damage or abnormal wear.
Replace the starter motor with a new one if there is any
damage or wear.
•
Visually inspect the commutator segments for discol-
oration.
Replace the starter motor with a new one if discoloration
is noticed.
Armature Inspection
•
Using the × 1 Ω hand tester range, measure the resis-
tance between any two commutator segments [A].
Special Tool - Hand Tester: 57001-1394
If there is a high resistance or no reading (∞) between any
two segments, a winding is open and the starter motor
must be replaced.
•
Using the highest hand tester range, measure the resis-
tance between the segments and the shaft [B].
If there is any reading at all, the armature has a short and
the starter motor m ust be replaced.
NOTE
○
Even if the foregoing checks show the armature to be
good, it may be defective in some manner not readily
detectable with the hand tester. If all other starter motor
and starter motor circuit components check good, but
the starter motor still does not turn over or only turns
over weakly, replace the starter motor with a new one.
